BELT-BUCKLE.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed January 7 1914. Serial No. 810,822:

To all whom it may concern Be it known that I, WILLIAM RUMBLE. J r. a citizen of the United States, residing at Cra-nford, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Belt-Buckles, of which the following is a specification.

My resent invention pertains to an improve belt buckle, the same being illustrated in the annexed drawings, in which Figure 1 is a longitudinal sectional view of the buckle with the locking or clamping plane in its released position; Fig. 2 a side elevation thereof, with the parts in the same relative positions; Fig. 3 a view-similar to Fig. 1, showing the,belt clamped or locked by the plate; Fig. 4 a side elevation with the parts in such locking position; Fig. 5 a perspective view of thebuckle, as viewed from the under or inner side; and Fig. 6 a detail perspective view, illustrative of the manner of securing the ends of the cross or belt-attaching bartogether.

The main object of the invention is to provide a simple and, at the same time, an eflicient buckle; one which is easy of manipulation in entering the free end of the belt into operative relation therewith, and

which likewise securely binds belt when once it is adjusted.

The construction is such that a'pull upon the belt only tends to cause the clamping plate to more firmly secure the belt a ainst movement, while the belt may be readi y released so that it may be drawn tighter, or the normally free end entirely withdrawn fromengagementwith the buckle. Again, a minimum number of parts are employed, which parts are non-separable.

The body of the buckle, formed of one or clamps the piece, may be said to comprise a face plate 1,

preferably made slightly convex or rounding in the direction of its length or from end to end, and from said plate extend side walls 2 and 3, the Walls being parallel to each other and at substantially right angles to the face plate. As will be seen, the walls are of less height at what may be termed the entrance end of the buckle, the margin or edges of the walls merging into the slightly rounded edge or lip 4 of the adjacent end of the face plate. Each wall is provided with a slot 5, said transverse plane and inclining downwardly and away from the face late, as they recede from the lip/4. Stated 1n another'way, the

slots lying in the same Extending through and freely movable in the slots 5 heads 6 of the side walls and confine the rod in place. Swiveled upon the rod is a clamping plate, comprising a body 7, having outwardy and upwardly inclined clamping wings or members 8, and at each end a downwardly-extending elongated lug 9 through which the rod 6 passes. 1 At what may be termed the rear end of the buckle, theside walls'are formed with' extensions 10, which are bent inwardly and united, forming a cross-bar to which one end of the strap. 11 is designed to be secured in any suitable manner. The ends of said extensions 10 are preferably secured together in the manner best shown in Fig. '6, wherein it will be seen that one member is provided relatively narrow tongue 12 which is is a cross-pin or rod 6, having with a passed through a slot formed in the overlying and slightly offset portion 13 of the other member, 10, the tongue beingbent down, as illustrated.

The construction thus set forth at once produces a rigidstructure which will not become distorted under strain, and which is also effective for the purpose designed, and easy of manipulation.

To secure the belt in place, the free end is passed inwardly past lip 4, into the space between the clamping plate and the under face of thebody 1. At such time the rod 6 is drawn rearwardly in slots 5, thereby causing the clamping plate to recede from the body 1, forming-a free passage-way for the belt, which is passed inwardly to the desired extent, or slightly beyond such point, whereupon a slight reverse pull u on the belt will cause the arts to assume t e positions illustrated in ig. 3. At such time the edges of the wings or member 8 will engage the belt and clamp the same against the inner face of the body 1, and .the more the strain the greater the pressure, the rod 6 passing upwardly in the slots and reducin the distance between the clamping'plate and the'body 1. By reason of the fact that the plate isswiveled upon the rod it has a tendency to rock under the initial pulling action of the belt and as the forward wing is thrown inwardly the rear wing is thrown outwardly toward the body, causing it. to contact with the belt and to be drawn forwhich bear against the outer faces.

wardly in the direction of the pull of the belt, thereby causing the plate as a whole to move with the belt and the rod 6 to slide along the inclined slots until the belt is so tightly clamped between the plate and the body that further movement is impossible.

Should the clamping plate assume the position shown in dotted lines in Fig. 1, the plate may be readily tilted to permit the ready insertion of the belt-end. This is accomplished by merely pressing upon the inwardly-projecting rear wing 8, and to facilirate such operation the sidewalls 2 are cut away, as at 14, to permit the insertion of the thumb or finger, as the case may be.

By providing the inturned lip 4: not only is a neat finish imparted to the buckle, but the lip lies close to the belt'and in a measure assists in the holding action of the buckle; particularly is this so where the belt is formed of thin or light material.

Having thus described my invention, what I claim is 1. Ina beltbuckle, the combination of a one piece body portion comprising a face plate curved in the direction of its length; side walls extending therefrom, each Wall being provided with an inclined slot, said slots converging with reference to the face plate; a rod slidably mounted in said slots;

a tiltable clamping plate carried by said rod, said plate being formed with wings inclining outwardly toward the inner surface of the faceplate; and means for securing one end 'ofa belt to that end of the buckle body remote from the clamping means aforesaid.

2. In a belt-buckle, the combination of a body plate; side walls extending therefrom, each ofsaid walls being formed with a finger recess adjacent its rear end; and a tiltable clamping plate movable toward and from the recesses, and the rear portion thereof lying adjacent said recesses when the plate is 'in its rearmost position.

3. In a belt-buckle, the combination of a body portion comprising a face plate 'convexly curved in the direction of its length; an inwardly-extending lip formed at one end of said plate; side walls extending from the face plate, each wall having an inclined straight slot formed therein, said slots 'inclining upwardly toward the face plate and lip, each of said walls likewise having a finger recess formed therein to the rear of the lower end of the slot; a rod seated and slidable in said slots; a clamping plate fulcrumed upon said rod, said plate having outwardly-extending wings; and a crossbar extending from the walls at the rear end of the buckle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
